error using CrystalDecisions

In my project I have

using CrystalDecisions.CrystalReports.Engine;

But this error marks me:

  

Error 1 The type or namespace name 'CrystalDecisions' could not be   found (are you missing a using directive or an assembly reference?)

But if I have Crystal Report installed, and I even added the reference:

  

PM > Install-Package CrystalDecisions.CrystalReports.Engine

How can I solve the error?

EDIT: I've also seen that to fix the error you should put the project with Target Framework .NET Framework 4.0 instead of .NET Framework 4.0 Client Profile and that has not solved my problem.
